I'm not 100% sure on the order I did things but I believe I first formatted the sd card. I created three folders on the card, Skydrive, Dropbox and Music. I created a folder on C: called SD and mounted the card to point to the C:\SD folder. i installed Dropbox and Skydrive and chose C:\SD\Dropbox and C:\SD\Skydrive as my sync folders when I installed Dropbox and Skydrive. I sync'd Skydrive which contains Documents, Photos and Videos. I don't sync the Music folder to any service since the folder is way too big for the space I have on either Dropbox or Skydrive so I just copied all my music to that folder manually. after my Skydrive sync'ed all the files, I went to Libraries and right-clicked on Documents, Music, Photos, and Videos and added a new location. I chose C:\SD\Skydrive\Documents, C:\SD\Music, C:\SD\Skydrive\Photos and C:\SD\Skydrive\Videos as the new locations, set those paths as the default locations and moved it to the top of the list. I removed all other paths except the "public" paths. I now have all my documents and media show up in their corresponding libraries, all apps can see the media in those locations, and all Documents, Photos and Videos are sync'ing from my Skydrive account and writing to the SD card without taking up any room on the C: drive. it's a thing of beauty really.
